The Gods Are Cruel. The common saying in Westeros, which everyone says when an ironic and painful thing happens. While they are Cruel, they can be somewhat strange in their actions. They were strange for never letting Balerion, The Black Dread, to fully die. The old but extremely stubborn Dragon would spend decades merely on the verge of crossing to the other side, yet never doing so. He wouldn't let anyone claim him, neither, using his weak strength to snap at anyone who dared which prompted any keeper to let him be. Until one day, that is. Baelon Targaryen, son of Viserys I Targaryen and Aemma Arryn, was able to survive the wretched decision his Father made on that fateful day. Unfortunately for him; His Mother could not. This eventually led Viserys to remarry and have more children, as Fate would have it. And as Fate would also have it, Balerion would regain his Vigor on the fateful day of Baelon's birth. Almost as if the gods planned this, it would seem, Baelon and Balerion eventually crossed paths and the two of them bonded. (Slow Updates) (Cover is AI Art I did online.)
